Abstract: This layered film includes a base layer and a sealant layer that becomes one outermost surface of the layered film. The base layer contains 77 to 99 parts by mass of a high-density polyethylene having a density of 0.942 to 0.970 g/cm3 and a melt mass-flow rate of 0.1 to 3.0 g/10 min under conditions of a temperature of 190° C. and a load of 2.16 kg and 1 to 23 parts by mass of an ultra-high-molecular-weight polyethylene having a density of 0.930 to 0.960 g/cm3 in a total of 100 parts by mass.

Abstract: A laminate has a substrate layer, an intermediate layer, and a fluorine-based resin layer in this order, and has a total film thickness of 400 ?m or less, in which a thickness of the fluorine-based resin layer is 20 ?m or more and 150 ?m or less and a water vapor permeability of the laminate is 0.5 g/m2/24 hours or less.

Abstract: The present invention provides an adhesive resin composition that is used for adhesion of a fluorine-based resin and is aimed at adhesion between fluorine-based resins or between a fluorine-based resin and a material other than a fluorine-based resin. More specifically, the present invention relates to an adhesive resin composition for use in adhesion of a fluorine-based resin, the composition including a polyethylene-based resin, an elastomer component, and a component having an epoxy group and a vinyl group, wherein a content of the polyethylene-based resin is 55 parts by mass or more and 90 parts by mass or less, a content of the elastomer component is 10 parts by mass or more and 45 parts by mass or less, the elastomer component and the component having an epoxy group and a vinyl group have a common repetition unit, and a content of the component having an epoxy group and a vinyl group based on a total amount of 100 parts by mass of the polyethylene-based resin and the elastomer component is 0.
